ANNUNCIATOR.

SPECIFICATION forming part of Letters Patent No. 400,050, dated March 26, 1889.

Application filedd'uly 24:, 1888. Serial No. 280,864. (No model.)

To all whom it may concern.-

Be it known that I, IRA S. BUNKER, a citizen of the United States, residing at Nevada, in the county of Vernon and State of Missouri, have invented a new and useful Improvement in Annunciators, which improvement is fully set forth in the following specification and accompanying drawings.

My invention consists of an annunciator constructed substantially as hereinafter set forth, whereby the expensive device heretofore employed in the oflice of a hotel or elsewhere is dispensed with, and other advantages are presented, as will be specified.

Figure 1 represents a front view of a portion of an annuneiator embodying my invention. Fig. 2 represents a horizontal section 011 line on m, Fig. 1, enlarged. Fig. 3 represents a view of a detached portion. Figs. 4: and 5 represent views of modifications.

Similar letters and numerals of reference indicate corresponding parts in the several figures.

Referring to the drawings, A represents the wall of rooms or apartments of a hotel, board ing-house, &c.; and B, the doors thereof.

0 represents a push-button of the order generally employed in electric annunciators, the same being connected with the wall A within one of the rooms and in communication with the annunciator D, which is located in the office or elsewhere of the hotel (he.

Passing through the wall A is a rod, 1, one end of which enters the casing of the pushbutton, so as to be engaged by the button proper when pushed'in, and the other end is adapted to engage with a plate, 2, located on the outside of the wall A, said plate being hinged to a back piece, 3, which latter is secured to said wall A, and has an opening, 4:, through which the rod 1 freely passes.

The operation is as follows: \Vhen service of a waiter, &c., is required, the push-button is operated, whereby the bell of the annunciator D is rung and attention directed to the number of the floor from which the call is made. Simultaneously therewith the plate 2 is forced out, and as it now projects into the hall or entry, the waiter, &c., who has proceeded to the floor named, has his attention directed to the projecting plate, and is thereby informed of the number of the room where he is required. He then closes the plate or restores it to its normal position and answers the call.

In Figs. 1 and 2 the plate is shown as having a vertical axis, in which case a spring, 5, is employed to throw out said plate, and in Fig. 4 the axis of the plate is horizontal, so that the plate drops by gravity when thrown out.

The plate in Figs. 2 and I is held in normal position by means of a catch, (3, which is readily overcome when pressure is applied to the button.

In Fig. 5 the plate is shown as pivoted to a piece attachable to the side of the door frame or molding, so as to close thereinto when thrown up, where it remains, due to gravity, until again forced outwardly and downwardly by the action of the push-rod 1 when the button is operated.

It will be seen that the device may be cheaply constructed, being composed of few parts, and is reliable in action, and that by its use the employment of a complicated and expensive annun'ciator in the office is avoided, as it is only required there to know the number of the floor from whence a call is made; hence for a building having three floors an annunciator with three numbers is sufficient, as in Fig. 3, where the call or alarm is exhibited as having come from the third floor.

It is evident that the plate 2 may be made to slide out by the operation of the rod 1 and returned by a spring suitably applied, in which case the hinges or pivots of said plate will be dispensed with, and a catch may be employed for temporarily holding the plate in its exhibiting position.

lzlavin g thus described my invention, what I claim as new, and desire to secure by Letters Patent, is

1. I11 an electric annunciator, the combination, with the push-button and rod thereof, of a movable indicating-plate, substantially as described.

2. The push-button C of an electric annunciator, in combination with the rod 1, attached thereto, and the swinging plate 2, secured to a frame adapted to be projected by the operation of said push-button, substantially as described.

3. A11 z'mlditiolml imliezitor for 2111 electric onnuneizttor, eons ting oi? a rod secured thereto and operated by th e p u sli-button of the ammuneizbtor, and movable pluite secured to a t'rmne 5 adopt-ed to be operated by contact with said rod, said parts being eombiued substantially as described.

-'l-. The combination of :1 pusli-lmtton, a red, at back plate through which. said rod PHSSOS, :l

[O movable plate connected to said back plate and adopted to be operated by the movement of said rod, a spring between said back plate and movable plate, and a catch adapted to hold said movable plate in closed positii'm, Sl'lbStfllltllllY as deSei-ibed.
